Beyond Imagination
Imagination is not an end, but it's a start with which we make brilliant ideas alive.

Electrical Analysis
We thoroughly conduct the following analyses to ensure that our products meet electrical specifications and achieve optimum performance. With well-experienced engineers and high standard analysis procedures, we work closely with R&D teams for debugging to provide high performance products to customers.
       •  Impedance Analysis
          We apply TDR (Time Domain Reflection) to measure PCB impedance.
       •  Audio Quality Analysis
          We analyze audio quality of platforms while recording and playing sound within an audio frequency           band to ensure that the system can meet high quality audio requirements.
       •  Video Analysis
          We analyze the analog and digital video output signal quality to ensure that the system can effectively           display videos and images.
       •  Digital Signal Analysis
          We analyze the parameters of a digital signal (frequency, spread spectrum, amplitude, ring,           overshoot, undershoot, rise time and fall time, jitter, setup time and hold time, timing sequence, bit           error rate, etc. ) to ensure that the system works properly.
       •  Power Noise Analysis
          We analyze the noise of each power rail to ensure that the system is stable.
       •  Component Analysis
          We analyze each component of the platform to check if it meets relevant voltage, current, and           temperature specifications.
       •  System Stability Analysis
          We ensure the system stability and compatibility with different CPUs and memories in corner           conditions (over-clock and reference voltage level changes).
Signal Integrity Simulations
We apply signal integrity and power integrity driven design processes to overcome the challenges of product design. Signal integrity simulations help connect logic design and physical routing design. Based on the simulation results, we develop routing guidelines to meet the AC/DC specifications for each high-speed digital signal. Signal Integrity simulations help us shorten the design cycle, solve possible issues, and minimize resource consumption prior to prototype development.
       •  Pre-Route Simulation
          Collect interconnection models, including IC models, package models, connector models, and cable           models. Apply corner case simulations to find the solution space. Generate routing constraints. Predict           the signal integrity for multi-board design.
       •  Post-Route Simulation
          Validate the routing results. Provide suggestions of register setting for better signal quality. Predict           electrical or routing changes.
       •  Correlation
          Compare the measurement results and simulation results. Validate simulation model and           methodology.
